Mechanism of action on insulin secretion
In the basal state, the plasma membrane of the β cell is hyperpolarized, and the rate of insulin secretion from the cell is low. When glucose is available, it enters the cell via GLUT2 transporters in the plasma membrane and is metabolized to generate intracellular ATP . ATP binds to and inhibits the plasma membrane K+/ATP channel. Inhibition of the K+/ATP channel decreases plasma membrane K+ conductance; the resulting depolarization of the membrane activates voltage-gated Ca2+ channels and thereby stimulates an influx of Ca2+ . Ca2+ mediates fusion of insulin-containing secretory vesicles with the plasma membrane, leading to insulin secretion.

In a meta-analysis of clinical trials including a trial in patients with stable cardiovascular disease, while serious cardiovascular events were infrequent overall, certain serious cardiovascular events were reported more frequently in patients treated with CHANTIX than placebo. These events occurred primarily in patients with known cardiovascular disease. Instruct patients to notify their healthcare providers of new or worsening cardiovascular symptoms and to seek immediate medical attention if they experience signs and symptoms of myocardial infarction or stroke.

Salicylates are derivatives of salicylic acid that occur naturally in plants and serve as a natural immune hormone and preservative , protecting the plants against diseases , insects , fungi , and harmful bacteria . [ citation needed ] Salicylates can also be found in many medications , perfumes and preservatives. [ citation needed ] Both natural and synthetic salicylates can cause health problems in anyone when consumed in large doses, [ citation needed ] but for those who exhibit salicylate sensitivity (also known as salicylate intolerance ), even small doses of salicylate can cause adverse reactions.
